Controlling borders is fundamental to sovereignty, the point being that a sovereign nation decides how porous the borders ought to be. To cede that control significantly reduces the self-determination of the people within the border, even if the decision of exactly how porous does not vary between administering entities.

So, why should southerners accept all those northerners coming down? The southern people have no sovereignty on the matter. Oh and don't even get me started with those Scots :)

The UK is not and has never been in Schengen, so it has borders and has control of it. They just happen to have agreed to a deal with the rest of the EU to give EU citizens almost the same rights as UK citizens.

In other words, people voting LEAVE can't have a problem with border control as it is now, because the borders are controlled. The problem is of a very different (and sad) nature.

Sovereignty is widely considered an obsolete concept.
